Remember a couple of weeks ago when we talked about the big, unthinkable thing Kourtney Kardashian did while pregnant -- you know, changing her hair color? While most medical experts say it's safe to do so, there are still a lot of questions/judgement around the issue when women highlight or otherwise color their hair while carrying a child.

Until now Kourtney has been quiet on the matter of her new 'do, but apparently she's been feeling a bit of pressure to explain. So she took to her blog to defend her decision.

She said she researched her decision, spoke to her doctor, and took all the necessary precautions. She said she didn't use a product containing ammonia; she made sure it never touched her scalp; she was in her second trimester; and she was in a well-ventilated room. Check, check, check, and check -- she followed all the suggested guidelines.

Anyone who knows anything about me knows that I take caution in all the products I use all the time, but especially when pregnant.

She shouldn't have to defend her right to highlight her hair, but I'm glad she did. She'll hopefully save some other women who want a little boost of beauty while pregnant from similar scrutiny. Of course, there will always be those who feel the need to judge (as the comments on her blog post prove), but pregnancy is filled with so many things we must avoid and stop doing that are proven harmful, I don't think we need to stop everything that "might" be harmful. If we did, we'd be pretty much be confined to a bubble ... though even then there's the problem with plastic ...
